This guitar was most likely one of his first electric guitars, built by Jerry himself sometime in the early 80s. According to an interview he gave to GuitarWorld Magazine in 2014, Jerry worked at the Boogie Bodies shop and was offered to pick out one of the Boogie necks that the owner (Lynn Ellsworth) prepared to send to Eddie Van Halen.

Rest of the guitar Jerry allegedly built himself using instructions given to him by Lynn. He built the body in his high-school wood shop class,which included drilling all the holes and adding contours to the body. The hardware that he used is unfortunately a mystery, but it based of the pictures he used a single humbucker placed in the bridge pickup cavity, a Kahler tremolo system, and a locking nut.

According the June 1998 Guitar World interview "Jerry Cantrell Unchained" by Marc Weingarten, Cantrell dubbed the guitar "EMBO" and used for "Cut You In":

GW: There are some really interesting departures for you on this record. 'Cut You In', for example, is almost like a samba, but it has that bizarre, inverted riff.

Cantrell: I was pretty hammered when I wrote that tune – I just started humming this thing I had in my head, and I grabbed this guitar I made in high school – it's a white Strat that I call EMBO, which stands for Eat My Butt Out. Anyway, I grabbed the guitar and wrote it in about 20 to 30 minutes.

Frank Iero sold a homemade, 1-of-1 “partscaster” based on the Fender La Cabronita Borracha on his official Reverb.com shop. He mentions that he became enamoured with Fender’s La Cabronita Borracha after playing one at a barbecue at Gerard Way’s house just before My Chemical Romance reunited in 2019. However, due to how prohibitively expensive and difficult to find they were, Frank bought the parts to build the guitar online and assembled it himself.

Quoting the article. “Interviewer: And you have that gray Strat. ERB: Yeah, that’s a Frankenstein Strat.

Interviewer:Was that also a Japanese knockoff? ESB: I would not spray paint a real Stratocaster [laughs]. At the time I had a sunburst Stratocaster, but that [gray guitar] was basically Frankenstein parts. I bought the body, neck, and pickguard, and put it together. I may have taken the neck and the parts off the real Strat and put them on that guitar.” Was used on most of the albums and the Hoilday In Cambodia Music Video and according to East Ray Bay Rig Rundown, he still owns it.

One of the guitars made by Isaac Wood himself.

In this photo taken at Club Lingerie in Los Angeles, California on November 4th, 1991, Ken can be seen playing a black Partscaster gifted to him by his younger brother. He mentions that his brother gave him the guitar in the 2004 Golden Documentary. This guitar was likely used for the majority of the band's first studio album, Comfort, released in September 1992, as well as their second album, Magnified, released in March 1994.

In this video Fluff gets parts from stew mac to make a partscaster strat. This is considered a partscaster because, even though they are mostly fender parts, Fluff chose all the parts Individually and put it together himself. This includes the body, neck, pickguard, pickups, electronics, and hardware. For this guitar fluff chose a fender 50s strat body, fender neck, fender locking tuners, a goto bridge, and a fender prewired pickguard. Fluff chose a set of fender texas special pickups for the guitar.

MAIN INFORMATION

Paul Dean's main guitar during the early Loverboy days (not to mention Streetheart) started life as a 1964 Fender Stratocaster with a home-built neck that he completley rebuilt. The guitar featured many modifications/features that inspirte the later Odyssey and Hondo Paul Dean guitars.

• Home Built Telecaster style neck with a break at the 10th fret (and lots of hollow spots in the neck) which gave it that unique resonance. This was later reproduced on the home-built prototypes + Odyssey and Hondo guitars by routing 1/4" resonance slots under the fingerboard parallel to each side of the Truss Rod.

• Grover Machine Heads

• Presumably an alder Fender Stratocaster body, chambered, tuned, and filled/reinforced with Fir or Pine, another element in the tone. Part of the body chambering is filled in with DAP Plastic Wood.

• Pickups include 3 aftermarket single coils, possibly hotter than normal.

• Gibson Stoptail tailpiece for a bridge

• Metal backed, rubberized "Anti-Scratch" pickguard, which now is missing all the rubberized material from the front.

This was the guitar Paul used on almost all of Loverboy's hits including "Turn Me Loose", "The Kid Is Hot Tonight", and "Working for the Weekend", and he still uses it apparently in his home studio from the looks of a recent guitar lesson posted on Youtube called "Lesson for the Weekend" which provides MANY closeup shots of the guitar.

This is the entire story of this guitar's construction.

How did you get interested in building?

I knew a guy who made a bass, and I guess that I got the idea from him. The first instrument I ever built was a 6-string bass I made in high school work shop. Then I had this old Les Paul--I think it was the '58 double cutaway with the little round horns. I picked it up for $125.00 because the neck was broken. Ifixed it and traded it to a guy for a '64 Strat, which I ended up totally smashing onstage trying to imitate Townshend.

What did you do to fix it?

I was really broke at the time, and even though I had another guitar--a custom one that I wasn't crazy about--I wanted the Strat back so I decided to fix it myself. I glued the neck back together--it broke at the 10th fret--using LePage's Bondfast and three drumsticks fro splints. I held the whole thing together with an elastic bandage. Believe it or not, it turned out great even though it was missing a few chunks of wood.

Why did it sound good?

Because the neck had been glued and filled in places with plastic wood, it had a particular resonance that was unbelievable. Shortly after that I left the guitar in a hot car trunk and the glue softened, which made the neck go for a total shit. Then I put on a new Tele neck, but it sounded worse than ever. I tried everything to make it better. I took the finish off and shaved it down. I even soaked it in a the bathtub and put it in the oven. I ended up making a new neck with a joint in the same spot as the original break.

Did you ever do anything else to the neck?

Yes, and I've never revealed this before. I put a couple of hollow grooves under the fingerboard to help the resonance--they weaken the structure and allow it to vibrate in a certain way. Actually there are three grooves; one for the truss rod and two resonance slots.

What happened to that body?

I had to reinforce it because it was totally wrecked; I used either fir or pine. Then I mounted a different bridge in the wrong place, so I had to fill in the holes and start over. Finally I got the whole thing back together, but it still sounded awful, it had a great sustain, but no real tone. So I took a screwdriver and hammer and chiseled out a bunch of wood underneath the pickguard. But I carved away too much so I filled up the cavity with plastic wood--it turned out to be right on. That guitar had a totally unique sound. I used some of those ideas on my Paul Dean guitar, including the neck slots, the body cavity under the pickguard, and a three-piece hard rock maple neck that resonates like the one I patched together.

RME/LFC - Jane: Do you have a favorite guitar, one you prefer over others?

PD - Yes. I just got this new Les Paul. It's my favorite 'live' guitar. You'll see it in the video. It's the one in the hotel room. It is a pretty interesting guitar. It's called a Les Paul Axcess. I think it's Alex Lifeson - the guitar player from Rush - I believe it's the one that he's endorsing. I changed the nobs, picks ups, the things that hold the strap on, the tuning heads, the nuts where the strings go through - basically everything except for the wood and the paint.

Now there's another guitar that's my favorite. REALLY MY FAVORITE GUITAR. You'll see it on the "No Tomorrow" video. It's the guitar I played "Working For The Weekend", "Turn Me Loose", and "Jump" on AND the whole first two Loverboy albums, plus the album I recorded with Streeheart as well. It's the one I built in Edmonton in 1973.

At 6:40 in this video interview with Fender, Lyle Workman says:

I can only recall putting my first Telecaster together. This is in the early '90s, so I made a Partscaster and I used that when I was touring with Frank Black.
